    Hello there

    I am a new member, have just bought a 1996 Accord,one previous owner and a full service history, i have just recently taken it to a Honda dealer to be checked over, they adjusted the tappets which had been incorrectly adjusted by a previous garage, this has quitened it down but still sounds tappy but not overloud, i have found videos on youtube and heard various Honda engines with the same sound, a lot were about the same sound.
    The piston slap which appears to be only coming from one cylinder decreases as the engine warms up,i was told by the dealer that piston slap is not uncommon for this engine. This is my first Honda, hoping that someone could give me some feedback to this. The car performs well and has covered 99.000 miles.

    Many thanks
    Mike

    Hello and welcome to AOC.Could you post a video clip of this sound? piston slaps are rare on the Accords. Are you sure there is no damage to the rocker arm of the incorrectly set valve?if the rocker arm develops wear they can cause this noise or even a worn camshaft , I can't see how a incorrect valve adjustment can result to a piston slap?

    This is all a guess work without looking at the car, you may need to show this to a Honda specialist.

    I have first gen accord and it has this noise on cold start up and it sounds horrendous .I have changed the camshaft as the old worn had pitting and scoring with a brand new one and the problem didn't go away... until I examined the rocker arm heads to see they were well out of shape and were physically worn.

    Since I can't get new rocker arms any more it will do . Once the car is warmed up this noise dispersers 100% it depends how far you want to go throwing money at it for a quite car.

    Hi Mike and welcome.

    I got your message thanks...I've nothing to add to what CJ said really...if that's what the problem is then it's not the greatest of news...no doubt you'll be taking it easy on the engine until it gets fully warmed up.

    Hi there

    thanks for the enquiry, the tappets seem to have settled down a lot i had these readjusted by a Honda dealer i have been driving it quite a lot and seems to be getting better as time goes on so fingers crossed.
    They ran checks on it and diagnosed piston slap, this virtually disappears after the engine is nice and hot, still there but a lot quieter. apparently it is a known fault on some of these engines they tell me.
    I paid £600 for this car, it has good bodywork and interior, has only had 1 previous owner and has a full service history, with now 100,000 on the clock, yes i could have a recon engine fitted, but am happy with what i have got, at the end of the day how much money do you want to put into a car. she drives very well with plenty of power, and is good on fuel, i have been using premium grade fuel, but am not sure if this is actually making any difference. Will keep in contact and let you know how things are going.some Rover and Subaru engines also appear to suffer from this as so do lots of other makes and some from new.
    Regards
    Mike

    Hi there
    It is me again, I am a little bit confused as well, if you take your foot of the accelerator the noise completely goes away and as soon as i put it under load the noise comes back,if you have any thoughts on this please get back to me.

    well the possibilities on the source of that noise are a few namely

    worn wheel bearing.
    worn Axel's.
    worn clutch release bearings.

    without looking at the car can't say really.
